To AN whom 11u/,Lf conceive:

Be it known that we, )ELTON R. tintin-1N and HAMEL C. Semin?, citizens of the I ciprocntes :is the doors 13 i3 open :ind close.

lfnited e l es. residing et Philzfidelphio, in the count v ot Philadelphia and Starte of Pennsylvenin, have invented certain new and useful improvements in Automatic Transporting Apparatus; and we do hereby declare the following to be e full, clear, and exact description of the invention, such ns will enable others skilled in the nrt to which it nppertnins to make und use the seme.

ur invention relates to means for unloading boa-ts, cnrs, and other convey-onces used for the transportation of Coal7 stone, and like substances, hns for its object the dispensing with motor `for furnishing power to the oar or receptacle used to convey or transport the coal from the conveyance being unloaded to n place of storage, end consists in certa-in improvements in construction, which will be ifully disclosed in the following specification and claim.

In the tier.onipanyingT drawings, which forni part of this speoiiiontion, Figure l represents n side elevation of apparatus embodying our invention; Fig. 2, un end elevation of the seme; Fig. 3, en inverted plan view of the car detached; Fig. 4, n vertical longitudinal section of the cnr end the track; Fig. 5, o vertiori-l transverse section of the seine, and Fig. 6 a. plan View of n section of the track.

Reference being had to the drawings end the desigiiating characters thereon, the numeral l indicates the bottom sil 5, 2 the posts resting on the sills, 3 the top sills resting on the posts, 4 the beams, the whole constitutingy the framework of the structure; 5, the trucks resting on the top sills Il; 6, the rails on tho tineke; 7,the lloororbottoniextendingzieros under the tracks.

l?. i3 nre doors h to opt..- ,utw'nril under the :wijh-t .nd prissure of the loud.

ie contents ol the wheels 20 20, which engage the rails (i of the track 5. The sills i6 are provided with recesses in which e transverse bnr 2l re- The bar 21 is provided with n notoh 22, and

' nt each end of the bnr is nn eyebolt 23 23', to

one of which is attached n. wire cable 24, one end of which passes over shea-ves 25 26, secured to the supplemental bottoni l5, and is secured to the door 13 et one end :rnd neer the lower edge ofthe door, and the opposite end ot' the cable passes over shenve 27 and 'is se cured to the door 13 in .like nienner et the opposite end ofthe door. The c: ble 24 passes over sheaves 28, 29, and 'and is secured in like manner to the opposite door 13( sis shown in Fig. 3.

31 is a lever fulerunied :it on the sill 17, is provided with n late-h or head 33, which engages the bar 2l in the notch 22, and is held in engagement therewi th by the lienvy or weighted end 34 of the lever until it is disengaged therefrom by being; tripped by the inclined end of ,the lever striking e trans-verse rod 36 between the tracks 5 5, located et such points as to secure the discharge ol' the our et any desired place along the lower end of the track or structure. Thelever beiner disengaged from the bnr 2l., the weight of the load in the oer instnntly forces the doors 13 13 outward and tle lond is discharged.

Neer the upper end of the struct ure and be tween the tracks 5 n setting-block 37 seoured to the bottom 7, and es the car nscends the trnek the ber 21 strikes the block 37 which pushes the bnr 2l toward the front end of tlm our and closes the doors 1? 13, when the lever 3l automatically engages the bar 2l nud seizures the doors in closed position f until tht 1.' are again automatically released bv they lever strikingr against one of the trans verse rods 3S. rThe block 37 is provided with fu.. vertical groove 38 to nllord clearance for the heed 253 of Ythe lever 3l.

.with one of the rods 36, the doors 13 18 disenare provided with bearings 45,- having a vertica slot 46, which engage vertical guides 47 on the inside of the posts 2 2, as shown in Fig. 2, and to the shaft 43 is secured a counterweight 48by means of a stirrup or metallic strap. 49.

The friction produced by the cable passing over the' sheaves in congunetion with the counterweight is sufiicient to allow the loaded car to travel down the inclined track to the place where itis to be unloaded, during which time vthe lower shaft and its sheaves rise between the posts nearly to the upper When the oar has discharged its load or contents, the Weight of the lower shaft and its sheaves in coniunction with the counterweight will draw the car up the incline to the'position for reloading. In the descent of l the car the lever 31 is tripped by Contact gaged, and the load of the car discharged, and in the ascent of the ear theI doors are closed y by the bar 21 engaging the block 37 and l locked by the head 33 of the lever engaging the bar, both operations bein4 automatic and requiring no attention from t e nien engaged in loading the car.

Having thus fully described our invention, what We claim isv In a transporting apparatus, a track, a'car having laterally-swinging doors, longitudinal sills under the car, a transverse bar movable on said sills, connections between said bar and said doors, means for securing the doors in closed position, a tripping device for releasing the doors, a cable attached to the car, iXed sheaves and vertically-movable sheaves engaged by the cable, and a oounterweight attached to the latter sheaves.

In testimony whereof We aiIiX our signatures in presence of two witnesses.
